7.4
The SELV wiring MUST be with mains voltage rated non-metallic sheathed cable. The SELV wiring should be
physically separated and insulated from any mains supply or other cabling. Cut the outer sheathing back as little as
possible so that the insulating sheath almost reaches the terminal block. 1.5mm2 cable is recommended for cable
runs up to 8m. Cable runs over 8m are not recommended.
7.5
Make the appropriate electrical connections as shown in fig. 1, 2 and 3. When using surface wiring, that is not
contained in conduit, the cables must be securely clipped to the mounting surface close to the controller.
7.6
The LuminAir fan & light assembilies are supplied with flying leads thus the connections between the controller
and the LuminAir should be made in a mains voltage rated junction box or similar.
7.7
Double check the wiring making sure all connections are secure. Fix the controller & LED driver covers back on.
Do not over-tighten the screws and take care not to trap any wires when fitting the two pieces together.
8. TIMER ADJUSTMENT
(LuminAir T models only)
The electronic timer fitted to the LuminAir T is triggered automatically when the unit is switched on by means of a
remote switch eg. a light switch. The fan will run for an adjustable preset period (between 3 and 25 minutes) after
the lamp is turned off via the remote switch. The timer is factory preset at approximately 15 minutes.
BEFORE ADJUSTING TIMER ISOLATE TRANSFORMER CONTROLLER FROM MAINS SUPPLY.
8.1
The adjuster is located on the circuit board inside the transformer controller.
8.2
Using a flat bladed Screwdriver turn the adjuster clockwise to increase or anti-clockwise to decrease the over-
run period.
N.B.
If used in a lighting circuit, for reliable operation, we recommend a tungsten filament lamp. The manufacturers
of some flourescent and low energy lighting systems indicate that these can interfere with electronic timer circuits.
9. CLEANING THE LUMINAIR
BEFORE CLEANING ISOLATE THE SYSTEM FROM MAINS SUPPLY.
Remove the Bezel and wash by hand in warm soapy water. Leave to dry. Wipe the Lamp Housing with a damp
cloth before pushing the Bezel back on to the Lamp Housing.
10. LAMP REPLACEMENT
BEFORE REMOVING OR REPLACING THE LAMP ISOLATE THE SYSTEM FROM MAINS SUPPLY.
The Vent-Axia LuminAir is specially designed for use with the supplied 12V MR16/5.3 LED rated at 3W. The lamp
is a straight push in/pull out type. When Removing/Replacing any twisting movement of the lamp should be
avoided.
